NL600 TP in river trouble

[beyonder]

6-handed table. My image very LAG. Villain semifish but not totally wasted. He is getting fed up with my constant 3-bets pre and aggro game.

Villain UTG, 389 stack.
Hero CO, 1370 stack.

Hero has K [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/heart.gif[/img]

Fold is pretty standard here i guess. I dont think Villain bluffs 1 times in 3 in such board, or bets out worse King or something like TT.

Would like some comments on turn check also. Many would bet the turn, but I belive it is very bad betting that turn.
